V2I Communication-Enabled Real-Time Intersection Traffic Signal Scheduling

Abstract

Vehicle-to-infrastructure (V2I) communications offer great opportunities for developing applications for Intelligent Transportation Systems with real-time vehicle motion and driving specific information. In this paper, we propose a system that allows an intersection traffic signal controller to adapt to the arrivals of a priority vehicle in a non-invasive manner by using real-time vehicle positions collected via V2I. Our scheduling algorithm uses the real-time positions and the intersection's historical timing data to determine a minimum-disruption timing plan that allows the priority vehicle to arrive during a green phase for its signal. The results show that the priority vehicle can achieve noticeable delay reduction with a lower level of delay increase by the other vehicles. The work demonstrates the power of vehicle-to-infrastructure communication in enhancing transportation operation by participating in traffic control.
